+ """Extreme Gradient Boosting, which is an efficient implementation of
+ gradient boosting framework. This package is its R interface. The package
+ includes efficient linear model solver and tree learning algorithms. The
+ package can automatically do parallel computation on a single machine which
+ could be more than 10 times faster than existing gradient boosting
+ packages. It supports various objective functions, including regression,
+ classification and ranking. The package is made to be extensible, so that
+ users are also allowed to define their own objectives easily."""
